ABSTRACT:
Reaction of glyoxylic acid with a C.sub.3 to C.sub.6 alcohol capable of forming an azeotrope with water to form the C.sub.3 to C.sub.6 alkyl glyoxylate or alkyl glyoxylate alkyl hemiacetal, reacting the intermediate with acrylamide and optionally with a C.sub.3 to C.sub.6 alcohol to form the C.sub.3 to C.sub.6 alkyl acrylamidoglycolate or alkyl acrylamidoglycolate alkyl ether in essentially polymer free form which are readily converted by transesterification/etherification or transesterification/transetherification with methanol into predominately methyl acrylamidoglycolate methyl ether preferably in liquid form.
